I enjoyed this lesson because I was able to rewrite in my notes, comments that helped me to better understand Physics. With the way this lesson was organized, I learned about projectiles, simplified equations and how to use the equations to my advantage.
While I learned much, I would have greatly appreciated a review and explanation on sines, cosines, tangents, and theta. For instance, what are the values of sines and cosines? Are there any set values or do they come about from the equations? What is the value of tangent and theta? Is theta always the angle? Had there been a review on this material, I believe that I would understand more of kinematics than I do now.
Although I was not able to fully understand values and placements, I was able to remember and understand enough that I was able to work the simulation run without hesitation. I think that the simulation runs at the end of the lessons help the students use all their resources and everything they have learned in class to answer the question. I willingly rate this lesson with a four (4).

Subject: Good but not complete
It doesn't go over vectors as deeply as i would have liked, but it did help me understand prjectile motion better.
